Tasker is right up there with our lord Matias Duarte in the amount of love it gets from the Android community. There's really no other way to get anywhere close to the same kind of automation running on your device. The new v4.4 update adds even more functionality to this already robust app. Heck, you almost don't have to touch the phone anymore. That doesn't really sound as fun, though.

Actually, that's just part of the changelog (the new features). There are also huge sections of bugfixes and changes to existing functionality, which you can see on the Tasker site. Seriously, this app is like the most Android thing ever.
